Abstract:
Objective To retrospectively analyze the distribution and drug resistant characteristics of isolated pathogens （especially Gram-negative bacteria） in hospital and promote the rational use of antibacterial drugs. Methods The pathogens and drug sensitivity test results were collected from the whole hospital every quarter from July 2018 to March 2023, and were conducted retrospective analysis. Results A total of 14 844 pathogens were isolated and detected, including 4 757 Gram-positive bacteria （32.05%） and 10 087 Gram-negative bacteria （67.95%）. The detection rate of extended spectrum beta-lactamases Escherichia coli was 43.23%, and it maintained high sensitivity to carbapenems and enzyme inhibitors, and the sensitivity rate was about 99.00%. The drug resistance of Klebsiella pneumoniae was more serious, and carbapenem-resistant, multi-drug resistance and extensively-drug resistance appeared. In 2022，the detection rate of carbapenem-resistant Klebsiella pneumoniae was 54.82%; the detection rates of carbapenem-resistant Pseudomonas Aeruginosa and carbapenem-resistant Acinetobacter baumannii in non-fermentative bacteria were 22.02% and 74.34%, the detection rate of multi-drug resistant Acinetobacter baumannii was >70%. Conclusion The problem of drug resistance of Gram-negative bacteria was still serious, especially in Klebsiella pneumoniae and Acinetobacter baumannii. The problem of bacterial resistance poses great challenges to clinical treatment, and it is necessary to conduct regular monitoring and promote rational drug use.
